Abstract (en)
[origin: WO2016026807A1] The invention relates to polyurethanes obtainable by reaction of a) polyisocyanates A selected from optionally modified methanediphenyl 4,4'-diisocyanate, homologues of methanediphenyl 4,4'-diisocyanate containing a larger number of rings, prepolymers based on methanediphenyl 4,4'-diisocyanate and containing isocyanate groups, and mixtures thereof, b) compounds having at least two hydrogen atoms reactive towards isocyanate groups, containing b1) block copolymers of a polybutadienol and a cyclic ester as component B, and b2) diols as low-molecular-weight chain extenders and optionally triols as crosslinking agents with molar mass from 62 to 500 g/mol as component B2, c) optionally other polymeric compounds C having at least two hydrogen atoms reactive towards isocyanates, d) optionally catalysts D, e) optionally water E, f) optionally physical blowing agents F, g) optionally other auxiliaries and/or additives G.
